Method
1 Chop 75g (3oz) chocolate and melt in a bowl set over a pan of barely simmering water. Stir into custard, cool then chill.
2 Place sliced muffins in the base of a trifle dish and sprinkle with kirsch. Spoon two-thirds of cherry filling onto muffins then top with chocolate custard.
3 Whisk cream until soft peaks form then spoon onto custard leaving a gap in the centre.
4 Spoon remaining cherry filing into centre of the cream and decorate cream with chocolate curls (make with a peeler). Chill for 2 hours or overnight.
